Funny you should mention this. We got sleigh bells that have a metal ring at the end to go over the door knob and on two occasions we heard the bells going nuts and went downstairs to find LIndy running around the kitchen with them in her mouth. LOL That was really before she knew what they were for. Now she leaves them in place. As far as ringing them for play I guess you just let her out whenever she rings them and if she doesn't "go" I would put her in her crate (if you are crate training) and try again later, that's what we do.
